Similar to what I was thinking of posting.
Only he can help himself now and he seems to be choosing not to, so until he changes his mind about it and accepts help or asks for some, best to let him deal with it how he's chosen.
In another lifetime I might have taken a more active role in trying to help him at the very beginning, but I pretty much stopped inviting homeless friends in to live with me after my experience with Michael.... someone who made me wake up to the fact that you can't help someone unless they CHOOSE the help, even if you provide all their room and board, and etc. If they choose to remain problematic, they will, and he did.

Edit: Not to mention, when John and I moved here, we decided on the policy of NOT having any desolate friends live here with us for any reason, which was a smart decision.
